a cache benchmark, running in the cache:
http://www.gnagnaki.net/wiki/guide/atari/megaste/cache#benchmarks
It's interesting to see that sustained write is nearly as slow with cache than without cache, and that mixed read-write with cache is a little bit faster than (read/2 + write/2) with cache.
Each time you write something to memory, you write it in the cache and then the cache write it to ram. That's why the mixed test is a little bit faster than expected, there is enough time between two writes.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
